Hi I'm 16 years old. Last month I had my period around the 21 the weekend before New Years. I don't really have a regular period. I kinda have unprotected sex something's we put it in for like a totally of 2 mins so he can get harder and put on a condom. I have been stressing out about this for awhile and around the 19 I've been having brown discharge and it FEELS like I'm on my period down there any answers for me?
